Question

(1 pt) Find the absolute maximum and absolute minimum
values of the function
f (x) = x^4−10x^2−7
on each of the indicated intervals.
Enter None for any absolute extrema that do not exist.
(A) Interval = [−3,−1].
Absolute maximum =
Absolute minimum =

Answer 1

f(-3)=-16
f(-1)=-16
f(-sqrt(5)=-32
the derivative is zero at x=sqrt(5).
-32 is absolute minimum and
-16 is an absolute maximum

Answer 2
